Glen Research Product Information

Catalog Number: 10-1032-xx
Description: O4-Me-dT-CE Phosphoramidite

5'-Dimethoxytrityl-O4-methyl-2'-deoxyThymidine, 3'-[(2-cyanoethyl)- (N,N-diisopropyl)]-phosphoramidite

Formula: C41H51N4O8
M.W.: 758.85 
F.W.: 318.22 

Diluent: Anhydrous Acetonitrile

Coupling: No changes needed from standard method recommended by synthesizer manufacturer. Monomers that allow for UltraMILD deprotection are recommended (Catalog Numbers: dA: 10-1601-xx, dC: 10-1015-xx, dG: 10-1621-xx, dT: 10-1030-xx.) To avoid any exchange of the iPr-Pac group on the dG with acetyl, use the UltraMild Cap Mix A (40-4210-xx/ 40-4212-xx).

Deprotection: If UltraMild Monomers were used: 0.05M Potassium Carbonate in Methanol, 4hrs at Room Temp. DMT-Off Synthesis: Add 6uL acetic acid per mL 0.05M potassium carbonate in methanol. Dry under vacuum. Desalt per standard procedures. DMT-On Synthesis: Use a Glen-Pak Purification Cartridge (60-5100-XX/60-5200-XX) to purify and desalt the oligonucleotide. Dilute the 0.05M potassium carbonate in methanol with 100mg/mL Sodium Chloride to a final concentration of 1:4(v/v). Load onto the prepped Glen-Pak Cartridge and purify as normal. If Standard Monomers were used: 1) Prepare a solution of 10% DBU in anhydrous methanol. DBU (1,8-Diazabicyclo[5.4.0]undec-7-ene) is available from Aldrich (139009-25G) as is anhydrous methanol (322415-100ML). 2) Transfer the CPG to a clean, dry glass vial and add 1mL of the 10% DBU solution. 3) Seal the vial and leave for 5 days in the dark at room temperature. 4) Transfer the contents to a micro centrifuge tube and reduce under vacuum to a small volume. 5) Add 1mL of 10mM aqueous sodium hydroxide solution and desalt or purify the oligonucleotide using standard procedures.

Storage: Refrigerated storage, maximum of 2-8°C, dry

Stability in Solution: 2-3 days
